I've been eating dry biscuits since Monday. Mainly - and on the first day I started doing so, entirely- because I could n't down anything else.

Somehow, somewhere, some bug slipped past my defences and decided to squat in my stomach. Queasy, billowing days and nights.

Not great, and still not, but I can feel the slow advance of endorphins and general goodness unfurling across my once nauseous and still slightly tremulous stomach. Don't stop, keep going troops. On to Victory.
